Should "select XZ_DEC" be replaced with "depends on XZ_DEC"? XZ_DEC 
requires CRC32, so if "select XZ_DEC" is used, there needs to be also 
"select CRC32".

XZ_DEC may optionally use other XZ_DEC_* symbols, which the user will 
want to choose when building for an embedded system. With "depends on 
XZ_DEC" the user will see that there's more than a single option that 
affects the details of the XZ support in Squashfs.
